Configuration for Vectara query.

k: Number of Documents to return. Defaults to 10. lambda_val: lexical match parameter for hybrid search. filter Dictionary of argument(s) to filter on metadata. For example a

filter can be “doc.rating > 3.0 and part.lang = ‘deu’”} see https://docs.vectara.com/docs/search-apis/sql/filter-overview for more details.

score_threshold: minimal score threshold for the result.

If defined, results with score less than this value will be filtered out.

n_sentence_before: number of sentences before the matching segment

to add, defaults to 2

n_sentence_after: number of sentences before the matching segment

to add, defaults to 2
